Installation, Commissioning, Cleaning and Maintenance

Industrial Ethernet OSM/ESM

C79000-Z8976-C068-10

5.2 Installation

OSMs/ESMs can be installed in several ways:

• Installation on a 35 mm standard rail

• Installation on a SIMATIC S7-300 rail

• Installation in pairs in a 19" cubicle

• Wall mounted

Note

Remember that the OSM/ESM must only be installed horizontally (ventilation slits

top/bottom see Figure 25). To ensure adequate convection, there must be a

clearance of at least 5 cm above and below the ventilation slits. You should also

make sure that the permitted ambient temperature is not exceeded.

Preparations

1. Before installing, check whether the switch setting of the DIP switches is correct

for your application. (see Section 4.2.4.1)

2. Remove the terminal block for power supply and signaling contact from the

OSM and wire up the power supply and signal lines as described in Section

4.1.7.

3. Only for OSMs/ESMs with digital inputs:

When necessary, remove the terminal blocks for the digital inputs from the

OSM/ESM and wire the input signals as described in Section 4.1.8.
